Design for Manufacturing (DFM): 7 Principles, Process & Practical Guide

Key Takeaways DFM locks in 80% of cost at design stage: Design for Manufacturing (DFM) connects product requirements with manufacturing capabilities. By applying DFM principles early, engineers reduce redesign risks, improve product quality, and shorten production cycles from prototype to production. 7 principles quantify real savings: Each DFM principle comes with cost data — part count reduction alone lowers assembly time by ~42%. Tolerance tightening multiplies cost 1.5× to 20× depending on precisi......

How to Benefit from 3D Scanning Uses

The Diverse Application of 3D Scanning Methods 3D scanning has become a perfect tool in engineering, design, and manufacturing. By capturing the geometry, and surface texture of objects, 3D scanning techniques enable the creation of high-resolution 3D models with the best accuracy. While 3D scanning has existed for decades, recent advancements have made it faster, more precise, and accessible to both industry and enthusiasts. This article explores the main 3D scanning methods, their benefits, and the ......

How Much Electricity Does a 3D Printer Use? Energy Consumption and Cost Explained

Key Takeaways Desktop printers consume little electricity: Typical FDM printers draw 50-150W, costing $0.05-$0.30 per print regardless of duration. Industrial systems consume more but produce more parts: SLS/SLM machines draw 2,000-10,000W, but energy cost per finished part can drop to $0.07 with dense builds. Energy cost per part matters more than machine wattage: A 4kW SLS system producing 200 parts per build achieves far better energy efficiency per part than a 100W desktop printer producing one pa......

Laser Scanning: Improving the accuracy and efficiency of 3D printing

Laser scanning works by emitting a laser beam to a target object or surface and measuring the time it takes for the laser pulse to reflect back. These time measurements, combined with angular information, allow the scanner to calculate the highly accurate distance and direction of each point on the surface of the object. Multiple laser beams are fired rapidly from all angles to capture a dense set of 3D coordinates, which in turn build a 3D model of the object. The advantage of this process is that it......
